A Budew Pokemon is available for capture along the grassy parts of this area. There is also a cave entrance further up that leads to the Ravaged Path. You can get an ANTIDOTE inside. Psyduck can be captured in this cave as well, but it hardly ever shows itself during daytime.

Route 203

Your rival, Damion will challenge you to a Pokemon battle. He has 2 Pokemons -- a Starly and another which depends on your Pokemon of choice from Rowan's briefcase earlier in the game. You'll receive a 124 Exp, and P900 for winning. Return to the Pokemon Center to heal if you like, then continue along Route 203 and participate in some more Pokemon battles along the way.
